Coax Loss Calculator

Did you ever wonder if there was a “cost” to having long lengths of extra coax? Suppose you just ran a nice long length of coax to your new J-Pole antenna. You thought it would be approximately 100 feet, but it ended up being only 50 feet. Should you just coil up the extra 50-feet of coax? Or is it worth it to purchase a second, shorter length of coax? Hm . . . Let’s see . . .

Like most things in this world, the answer is “it depends”. But an excellent source of information is the coax lost calculator here: http://www.qsl.net/co8tw/Coax_Calculator.htm might yield a useful data item. Key: it depends greatly on the type of coax (not surprisingly) and (surprise, surprise) the operating frequency! HF frequencies are pretty resilient. However at VHF and UHF frequencies, coax is very, very lossy unless you buy very expensive, low-loss coax, e.g. LNR-400.

UPDATE 28-Dec-2017:All of the club analog and DSTAR repeaters at all sites are online and operational.

D*STAR Digital Repeaters:
DV 146.4125Mhz (+1)offset, "C" node
DV 443.0625Mhz (+5)offset, "B" node
DV 1290.00MHz (-20)offset, "A" node
DD 1247.00Mhz Simplex Data
(Note: The D*STAR repeaters are not linked together by default. If desired, you can manually link them to the same DPLUS reflector to get the same effect.)
